It’s an older game (1998) but it has a 92 metascore and is definitely worth playing, if you’re into games. If not, makes an okay gift for someone who is I think. Amazon account required, presumably valid payment info as well. Unsure of functionality outside of the US
Aside: If anyone's interested, I typically trawl for bundles and free games a lot, I can post others I find, or steep discounts or whatever.
